Patent number: 8543266Abstract: Methods, systems, and computer-readable media are described herein for using a modified Kalman filter to generate attitude error corrections. Attitude measurements are received from primary and secondary attitude sensors of a satellite or other spacecraft. Attitude error correction values for the attitude measurements from the primary attitude sensors are calculated based on the attitude measurements from the secondary attitude sensors using expanded equations derived for a subset of a plurality of block sub-matrices partitioned from the matrices of a Kalman filter, with the remaining of the plurality of block sub-matrices being pre-calculated and programmed into a flight computer of the spacecraft. The propagation of covariance is accomplished via a single step execution of the method irrespective of the secondary attitude sensor measurement period.Type: GrantFiled: October 3, 2011Date of Patent: September 24, 2013Assignee: The Boeing CompanyInventors: Rongsheng Li, Tung-Ching Tsao, Arunkumar P.

Patent number: 7822812Abstract: Techniques for sharing content information between members of a virtual user group without compromising the privacy of the members. A user can identify content information to be shared with other members of a virtual user group using a user computer system. The content information is then communicated to the other members of the virtual user group and can be accessed by members of the virtual user group in such a manner that the privacy of the user and of the other members of the virtual user group is not compromised. The present invention preserves user privacy by controlling and minimizing the amount of user-related information available/accessible to server systems hosting the virtual user groups.Type: GrantFiled: January 3, 2007Date of Patent: October 26, 2010Assignee: Stratify, Inc.Inventors: Rakesh Mathur, Ramesh Subramonian, Ramana Venkata, Pangal P.

Patent number: 7456098Abstract: Stacked via pillars, such as metal via pillars, are provided at different and designated locations in IC chips to support the chip structure during processing and any related processing stresses such as thermal and mechanical stresses. These stacked via pillars connect and extend from a base substrate of the strip to a top oxide cap of the chip. The primary purpose of the stacked via pillars is to hold the chip structure together to accommodate any radial deformations and also to relieve any stress, thermal and/or mechanical, build-tip during processing or reliability testing. The stacked via pillars are generally not electrically connected to any active lines or vias, however in some embodiments the stacked via pillars can provide an additional function of providing an electrical connection in the chip.Type: GrantFiled: April 13, 2006Date of Patent: November 25, 2008Assignee: International Business Machines CorporationInventors: Habib Hichri, Xiao H.
